Yeah- you should have mentioned that it's just a cabinet in the title.
I saw this last year. He didn't have a whole lot of older stuff worth getting. There was a cabaret Pac that he was 'sure he had a working board for' that would be 3 or 4 hundred. I spent a lot of time digging through some boards he had and pulled out several. He wanted like ebay prices for untested boards with a small discount since he can't test it. I walked away from 4 or 5 Pacman boards once he established he wanted about $60 each. Chip picked them up with some other stuff. Too rich for my blood.
I did wind up getting a couple of Space Invaders sets and a Peter Packrat daughtercard for what I considered to be fair. I went through a LOT of boards and that's about the best I could find. Somebody obviously got the best stuff in the past.
He's an operator and maintains a few locations. He sells off stuff to have some more room, but he's not desperate at all.
The Tempest cab looked OK, but you would need the guts. I think he offered it at a (lower) price last year, but I've got no use for it. It's a cab and a harness. At least the control panel is still there.
